Ever wondered what it would be like if the Great Barrier Reef could fit on a pinhead? Meet Patrick El-Khoury, the scientist who explores landscapes just as vast and complex as Australia’s maritime wonder, but about 10 million times smaller. Armed with his trusty Tip-Enhanced Raman Spectroscopy (TERS) instead of a fedora and whip, this modern-day explorer ventures into realms where molecules are mountains and atoms are like grains of sand.
Picture this: while most of us struggle to keep our desks organized, El-Khoury is mapping out territories so tiny that a dust mite would look like Godzilla in comparison. At Pacific Northwest National Laboratory, he’s the guy who looks at the world’s smallest “local neighborhoods” – places where molecules hang out and do their thing, each with their own unique personality and quirks.
“Rules are meant to be broken,” he quips about the bizarre behavior of molecules at this scale, sounding more like a quantum mechanics rebel than your typical lab coat-wearing scientist. And he’s right – down here, the textbook rules of chemistry and physics start to look more like loose guidelines, with molecules breaking convention like teenagers at prom.
His work is like being a real estate agent for atoms, checking out the “nano-basins” and “local environments” where molecules set up shop. Only instead of looking for good school districts and property values, he’s investigating why some spots on a catalyst are party central for chemical reactions while others are more like molecular ghost towns.
Perhaps the most entertaining part of El-Khoury’s work is his relationship with device scientists. With a hint of mischievous glee, he admits he’s not the guy making wafer-scale devices, but he can “probably generate enough useful information about existing and prototypical devices to inform — or just annoy device scientists.” It’s the scientific equivalent of being that friend who points out all the plot holes in your favorite movie.
Using his arsenal of spectroscopic tools (and “enough lasers,” because apparently there’s such a thing as too few lasers), El-Khoury peers into a world where the conventional rules of optical physics go out the window. It’s like he’s discovered a tiny universe where even the most basic assumptions need to be double-checked, and every new observation could overturn decades of textbook wisdom.
So next time you’re feeling overwhelmed by the size of your to-do list, remember Patrick El-Khoury, the scientist who navigates landscapes smaller than your smallest problem, armed with nothing but light and an insatiable curiosity. Just don’t ask him to make you a wafer-scale device – he might start telling you about all the ways it could go wrong at the nanoscale, and trust me, that’s a very, very small rabbit hole you don’t want to fall into.
